wanna-snif nppnqationmediebniafy 'Ifhis invention relates to certain new and useful improvements in water ski, and the primary object thereof isfto provide a ski which rides more nearly on the surface ofv the water, whichis not susceptible to easy tipping, and which permits the user to easily make turns without loss of balance.

A further object of the invention is to provide a ski which has improved water wings for assuring return of same to normal position prior to commencement of the back stroke.

In the' drawings Y l 'F ig. l is a side elevation of the invention;

Fig. 2 is a top plan view, andv Fig. 8 is an enlarged section on line 3 3 of Fig. l. i

In proceeding in accordance with the present invention, a pontoon is employed having a foot engaging top l, sides 2 depending from. the top, and a' bottom 3, these parts being connected to form an air sealed chamber. The front ends of the sides 2 curve upwardly at 4 toward the toe part of the ski whereby the toe part is raised.

The sides 2 are formed with extensions l4 that project below the bottom 3 and constitute a double keel. The forward ends of the keel members 4 are also curved upwardly and terminate adjacent the bottom. The top l has a heel support 5 at its rear equipped with a securing strap 6, while the forward part of the top isvequipped with a securing strap 7 to engage the toe portion of the foot.

The keel members 4 receive therebetween the resistance or water engaging wings 8,V which wings are supported by and from the keel members by means of transverse pins 9. The wings may be formed of sheet metal and have curled upper ends 10 receiving the pins 9 and flange sides 11, the flanges being tapered and having theirv widestends engageable with the pontoon bottom 3 so as to space the bodies of the r wings from the pontoon bottom upon the forward stroke of theski, thus assuring the wings freely and promptly gravitating to the position of Fig. l,V upon the end of the forward stroke. rlhe flanges thus Vact to prevent any possible sticking or adhering of the wings to the pontoon bottom. Stop pins l2 carried by one of the keel-members are employed to arrest forward movement of the wings.

From the foregoing it will be seen that l a double keel is provided which prevents 1.,..i9ae sel-inane.28eme.,

tipping, and thattherilassare. carried 'by the keel and are held out of area-or sur` face contact with the bottomy of the pontoon, thus assuring proper functioning of each and all thereof. VThe two keelsact to prevent loss of balance in turning andby the upwardly tapered construction ofthe keels and pontoon sides the ski rides higher on the surface of the water and thus easily thereon( s l What is'claimed is e 1. ln'a water ski, a pontoon having atop, bottoinand sides, the sides being extended below the bottom to form a` pairof spaced 'i keel members, said sides being curved upwardly andV forwardly from their lower edges, a series of wings having tapered side flanges disposed between the keel members and having their widest parts engageable with the Apontoon bottom, pinson which thev wings are pivotally mounted connected to the keel-members, and stops carried by one` of the keel members to engage and arrest forward movement of the wings.

' 2. Ina water ski, a pontoon having a top, bottom and sides, the vsides beingeXtended below the bottom to forma pair of spaced keel members, said sidesV being curved upwardly and forwardly from "their lower if;

edges, a series of wings pivoted between the keel-members, and spaced below the pontoon bottom, and means to arrest -forward move- Y ment of the wings.

8. l'n a water ski, a pontoonV having bottom and sidesthe fronts of the sides and the front of the bottom being curved upwardly and forwardly, the sides being eX- tended below said bottom to form a pair of spaced keel members, the fronts of said "Y" extensions of the sides rbeing curved upwardly and forwardly and substantially merging into thefirst named curved parts of the sides and bottom and water resisting X means between the keel members. v

4. In a water ski, a pontoon, wings piv-y otally carried by the pontoon and projecting below the bottomk thereof, side Vflanges on the wings engageable at'theirv side edges with the pontoon bottom to hold the bodies of the wings spaced from the bottom, and means to arrest forward movement -of the wings; l Y

A5. In a water ski, a pontoon, wings pivotally carriedl by thepontoon and projecting i below the bottom thereof, means carried by eac-,h wing to engage the pontoon body to hold the bodies of the wings spaced from Jzbe'bottom, and means to arrest forward Vmovement of the wings.

6. In a water ski, a. pontoon, wings pivotaHy carried by the pontoon and projecting below the bottom thereof, means carried by each wing to engage the'pontoon body to hold the bodies of the wings spaced fromthe bottom, and a stop for each wing to arrest forward movement thereof.

and having side flanges formed to have ltheir side edges engage the pontoon bottom, to prevent Contact of the bodies of the wings with the pontoon bottom.

In testimony whereof I aiX my signature.
